High performance drop-in replacement for the factory air filters; fits OEM M3 V8 (US cars only) airboxes for improved airflow and performance. Starting with its outer frame, BMC uses a special soft rubber material made in a process called "full molding", which not only provides a much tighter seal around the filter, but also eliminates any potential cracking or breaking of the filter. The filter element itself is made of a washable cotton material that provides nearly 40% greater airflow than paper, enclosed in an alloy mesh screen which helps the filter keep its shape and protects against larger debris and dirt. The increased flow of air through the filter provides a steady stream of clean air to the engine, resulting in much more consistent and efficient power.FEATURES:Fits all USA BMW E90/92/93 M3 vehicles (2007-2013) (Fits USA cars only)FS.BMW.E9X.BMC(2007-2009) Price: 140$FS.BMW.E9X10.BMC(2010-2013) Price 140$Lifetime filters are washable and re-oilableOriginal equipment for the Ferrari Formula 1 Team and Ferrari GT race team, as well as Porsche Motorsports, Mercedes Benz F1 and GT race teams, and the AUDI Motorsports TeamNOTE: Be sure to select the filter for the proper year range of your vehicle.
